Do you have an insatiable desire to achieve your goals?

Are you very competitive - even against your children?

Do you have a strong desire for recognition?

Do you enjoy doing lots of different things at once?

Are you always in a rush to finish things?

Are you impatient?

Are you quick to lose your temper?

Are you unhappy doing nothing?

Are you self critical?

Do you feel impatience towards others if they are not doing things quickly enough?

Do you like working against the clock?

Do you often direct your anger towards yourself?

If you recognise these things in yourself, then you could be a Type 'A' Personality.

So what? I hear you asking. Psychologists believe that people with this type of personality are more likely to suffer from stress related illness, particularly heart disease.

A lot of research has been done into personality types. Do certain types of people apply for certain types of job etc? Some of the things that research has highlighted seem to simply be stating the obvious. Of course your personality type will influence the work you look for or the lifestyle you lead! You wouldn't expect someone who is painfully shy to become a politician or an actor. Likewise an adrenaline junkie would not be happy doing accounts or filing. Well now it seems that your personality type will also influence the type of illnesses you may be likely to develop.

In 1974, a report was published by Meyer Friedman and Ray Rosenman, suggesting that the link between type A personality and coronary heart disease (CHD) was very high indeed.

They followed a group of men over the course of 8 years and found that 257 of them developed CHD. Out of that 257 a staggering 70 percent were found to have type A personalities.

People with a type B personality lack the aggressive tendencies and are generally more relaxed in their approach to life. There seemed to be no relationship between type B personalities and heart disease.

Of course it doesn't mean that anyone with a type A personality will suffer from heart disease, only that it could indicate possible problems later in life.
